Semisynthetic cephalosporin antibiotic III generation for oral administration in a broad spectrum of action.
It is bactericidal. The mechanism of action is due to the inhibition of the synthesis of the cell membrane of the pathogen. Cefixime is resistant to the action of? -lactamases produced by most gram-positive and gram-negative bacteria.
In vitro cefixime is active against gram-positive bacteria: Streptococcus agalactiae;
Gram-negative bacteria: Haemophilus parainfluenzae, Proteus vulgaris, Klebsiella pneumoniae, Klebsiella oxytoca, Pasteurella multocida, Providencia spp., Salmonella spp., Shigella spp., Citrobacter amalonaticus, Citrobacter diversus, Serratia marcescens.

(including methicillin-resistant strains), Enterobacter spp., Bacteroides fragilis, Clostridium spp.
PHARMACOKINETICS
When administered, the bioavailability of cefixime is 40-50% regardless of food intake, however, the C max of cefixime in the serum is achieved faster by 0.8 h when taking the drug with food.
The binding with plasma proteins, mainly with albumins, is 65%. About 50% of the dose is excreted in the urine unchanged for 24 hours, about 10% of the dose is excreted with bile. T 1/2 depends on the dose and is 3-4 hours. In patients with impaired renal function with KK from 20 to 40 ml / min T 1/2increases to 6.4 h, with a KK of 5-10 ml / min - up to 11.5 h .

SPECIAL INSTRUCTIONS
With caution should be used in elderly patients, patients with chronic renal failure or pseudomembranous colitis (in the anamnesis), in children under 6 months of age.

With prolonged use, there may be a violation of normal intestinal microflora, which can lead to the growth of Clostridium difficile and cause the development of severe diarrhea and pseudomembranous colitis.

In patients with a history of allergic reactions to penicillins, there may be manifestations of hypersensitivity to cephalosporin antibiotics.

During treatment, a positive direct Coombs reaction and a false positive urine reaction to glucose are possible.

OVERDOSE
The tubular secretion blockers (allopurinol, diuretics) delay the excretion of cefixin by the kidneys, which can lead to an increase in toxicity.

Cefixim reduces the prothrombin index, increases the effect of indirect anticoagulants.

Antacids, containing magnesium or aluminum hydroxide, slow the absorption of cefixime.
